I have a 2016 w213 e220d
Car displays cannot read fluid level on adblue, also have the engine management light on, it does show level briefly sometimes but then goes off, I have 2 fault codes, U05A308, U05A387, fault pointed towards nox sensor, I replaced the nox sensor but made no difference, any idea or tips would be great

 

I have the same issue. W213 2017 220d. Intermittent reading on the adblue on the dash. If the tank is replaced do they replace any of the control modules or anything else?

 

Hi Fault U05A308 is Adblue pump module has a malfunction ie There is a signal fault or the message is faulty MB want you to replace the whole Adblue tank I am working on a solution with a friend of mine stay tuned.

Thanks Paul.

I had this too, same model and year. It came up with the message engine will not start in xxx miles, then after a few days it would reset and it could read the adblue level, but then fault would return. Had it on and off for a few months. Took it to MB who updated software, fault returned after a week or so, took it back and they updated software again (said there had been a new adblue update), but it returned again. Then they replaced a sensor on the tank from a salvage one they had but only lasted a few days then fault returned. They said if that happened it’d be a whole new tank needed cos it comes with the sensor and pump in one unit costing about £1500. I got the serial number of the tank I needed and got a salvage one from eb*y. Indie fitted it in an hour and thats been ok for a year now. Good luck!

 

Any chance you have the serial number to hand for the adblue tank? I've just been quoted one from MB for £983 exVAT but they wont give me the part number? Cheers Gary
